Everyone, meet Cosmo. Today, Cosmo's owner had a medical emergency. The smart pup immediately went to look for help. A good samaritan saw Cosmo and tried to get closer, Cosmo led them to his owner and 911 was called. Thanks to this, Pumper 15 and Rescue 31 were able to assist and transport the patient, saving his life. Who's the goodest boy of them all?
